作为身体工作能力的综合指标,通常都采用(?)_(O_2)max。(?)_(O_2)max与多种长距离跑的时间密切相关(r=0.83～0.91)。但是,在高级运动员实验组中,发现(?)_(O_2)max与工作能力之间没有什么本质联系。同时还知道,(?)_(O_2)max接近甚至相同的运动员,在长距离比赛中却显示出很大变异性。我们知道,耐力项目的比赛成绩,不仅仅决定于运动员有氧功率的大小,还取决于利用其最大有氧供能功率,即(?)_(O_2)max来维持其专项速度的时间长短。可见,要评价工作能力,必要揭示出有氧供能与无氧供能(或者
As a comprehensive index of physical working ability, it is usually used (?) _ (O_2) max. (?) _ (O_2) max is closely related to the time of long distance running (r = 0.83 ~ 0.91). However, in the experimental group of senior athletes, it is found that there is no essential relationship between (?) _ (O_2) max and working ability. At the same time, we know that (?) _ (O_2) max is close to the same athlete and shows great variability in the long distance race. We know that the endurance race results depend not only on the athlete’s aerobic power but also on how long it takes to maintain his or her specific speed using its maximum aerobic power, (?) _ (O_2) max. Visible, to evaluate the ability to work, it is necessary to reveal the aerobic and anaerobic energy supply (or
